海岛礁地表覆盖演变分析对海岛礁开发利用、海洋资源保护、海洋经济开发等具有重要作用。基于高分辨率遥感影像, 利用遥感与地理信息系统(geographic information system, GIS)技术, 对西沙宣德群岛之赵述岛2008—2014年间的地表覆盖情况进行分类提取并变化检测, 形成赵述岛多期地表覆盖现状图。构建了海岛礁地表覆盖分类体系, 在此分类基础上采用地表覆盖转移矩阵, 结合净变化量、交换变化量、总变化量等变化参数对研究期内赵述岛地表覆盖变化进行了分析。

Analysis of island reefs’ land cover evolution plays an important role in the exploitation of island reef, the conservation of marine resources and the development of marine economy. This paper is based on high resolution remote sensing images. With the usage of technologies of remote sensing and GIS (geographic information system), a series of experiments of land cover classification, extraction and change detection were done for Zhaoshu Isle, which belongs to the Xisha Xuande Isles, from 2008 to 2014; eventually Zhaoshu Isle long phase surface coverage status was formed. A classification system of island reefs’ land cover was built as the basis. With the usage of land cover and transfer matrix, along with the consideration of change parameters such as net changes, exchange variation and total amount of changes, an analysis of the land cover variation of Zhaoshu Isle has been performed.
